TECHNICAL FIELD

[0001] The application relates to the technical field of chemical equipment, and in particular relates to a tubular reactor. BACKGROUND

[0002] The tubular reactor is a continuous operation reactor in a tubular shape with a large length-diameter ratio, and belongs to a plug flow reactor. The tubular reactor is widely applied to the chemical industry, petroleum industry, food industry, pharmaceutical industry and the like, and can realize a high-efficiency and continuous reaction process. The unique structure and design of the tubular reactor make the tubular reactor an indispensable equipment in many industrial fields.

[0040] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 2 The present application will be further described in detail.

[0041] The embodiment of the present application discloses a tubular reactor.

[0042] With reference to Figure 1 , the tubular reactor comprises a frame 1 and a reaction tube 11 mounted on the frame 1. The frame 1 is provided with a buffering device 2 for buffering the vibration of the reaction tube 11, and the buffering device 2 comprises a first buffering mechanism 21 and a second buffering mechanism 22. The first buffering mechanism 21 is arranged on the frame 1 and is used for buffering the vertical vibration of the reaction tube 11. The second buffering mechanism 22 is arranged on the frame 1 and is used for buffering the lateral vibration of the reaction tube 11.

[0043] With reference to Figure 1 , the frame 1 is mounted with a mounting bottom plate 12. The shock-absorbing dampers 13 are fixedly mounted at the four corners of the lower surface of the mounting bottom plate 12. The mounting bottom plate 12 is connected with the frame 1 through the shock-absorbing dampers 13.

[0044] With reference to Figure 1 and Figure 2The first buffering mechanism 21 comprises a buffering plate 23 and an arc spring sheet 24. The buffering plate 23 is fixedly installed on the lower side wall of the reaction tube 11. The connection between the buffering plate 23 and the reaction tube 11 is covered with the sound-absorbing cotton 14. The arc spring sheet 24 is fixedly installed on the lower surface of the buffering plate 23 and is in abutment with the upper surface of the installation base plate 12. The vibration of the reaction tube 11 drives the buffering plate 23 to move, and the movement of the buffering plate 23 drives the arc spring sheet 24 to deform. The arc spring sheet 24 converts the vertical vibration force generated by the reaction tube 11 into the elastic deformation potential energy of the arc spring sheet 24, so as to buffer the vibration impact force.

[0045] With reference to Figure 1 and Figure 2 The second buffering mechanism 22 comprises a buffering frame 25, a buffering rod 26, a buffering block 27, a first buffering spring 28 and a second buffering spring 29. The buffering frame 25 is fixedly installed on the upper surface of the installation base plate 12. The side wall of the buffering frame 25 is provided with a horizontal sliding hole 15. The buffering rod 26 is slidingly installed on the buffering frame 25 along the length direction of the buffering frame 25, and the end of the buffering rod 26 is located in the sliding hole 15. The length direction of the buffering rod 26 is perpendicular to the length direction of the buffering frame 25. The buffering block 27 is slidingly sleeved on the buffering rod 26 along the length direction of the buffering rod 26, and the buffering plate 23 is fixedly installed on the upper surface of the buffering block 27. The first buffering spring 28 is fixedly installed on the inner side wall of the sliding hole 15 of the buffering frame 25 and is connected with the side wall of the end of the buffering rod 26. The second buffering spring 29 is fixedly installed on the buffering rod 26 and is connected with the buffering block 27.

[0046] With reference to Figure 1 and Figure 2 When the reaction tube 11 generates vibration in the horizontal direction, the movement of the reaction tube 11 drives the buffering plate 23 to move, the movement of the buffering plate 23 drives the buffering block 27 to move, the movement of the buffering block 27 drives the second buffering spring 29 to contract or stretch, and the second buffering spring 29 buffers the movement of the buffering block 27. The movement of the buffering block 27 drives the buffering rod 26 to move, the movement of the buffering rod 26 drives the first buffering spring 28 to contract or stretch, and the first buffering spring 28 buffers the movement of the buffering rod 26. Thus, the horizontal movement of the buffering rod 26 and the buffering block 27 is buffered through the deformation of the first buffering spring 28 and the second buffering spring 29, and the work of buffering the vibration force generated by the reaction tube 11 in the horizontal direction is completed.

[0047] With reference to Figure 1 and Figure 2The installation base plate 12 is provided with a detection mechanism 3 for detecting the durability of the arc-shaped spring sheet 24, the detection mechanism 3 comprising a detection block 31, a deformation ball 32, a detection plate 33, a sensing color-changing sheet 34 and a force transmission assembly 35. The detection block 31 is fixedly installed on the upper surface of the installation base plate 12. A vertical moving groove is formed in the upper surface of the detection block 31. The deformation ball 32 is placed on the bottom wall of the moving groove. The detection plate 33 is vertically slidably installed on the detection block 31, and a part of the detection plate 33 is located in the moving groove and in contact with the deformation ball 32, and another part of the detection plate 33 is located above the detection plate 33 and in contact with the buffer plate 23. The sensing color-changing sheet 34 is fixedly installed on the outer side wall of the installation base plate 12. A reinforcing rib plate 38 is arranged at the connection between the installation base plate 12 and the sensing color-changing sheet 34. The force transmission assembly 35 is arranged on the installation base plate 12 and is used for transmitting the pressure received by the deformation ball 32 to the sensing color-changing sheet 34.

[0048] With reference to Figure 1 and Figure 2 The force transmission assembly 35 comprises a force transmission rod 36 and a force transmission plate 37. The force transmission rod 36 is horizontally slidably installed on the detection block 31, one end of the force transmission rod 36 is located outside the detection block 31, and the other end of the force transmission rod 36 extends into the moving groove and is connected with the deformation ball 32. The force transmission plate 37 is fixedly installed on the end of the force transmission rod 36 located outside the detection block 31 and is in contact with the sensing color-changing sheet 34 after the deformation ball 32 is deformed.

[0049] With reference to Figure 1 and Figure 2 When the reaction tube 11 vibrates to drive the buffer plate 23 to move, the buffer plate 23 moves to drive the detection plate 33 to move, the detection plate 33 moves to drive the deformation ball 32 to be deformed, the deformation ball 32 is deformed under force to drive the force transmission rod 36 to move, the force transmission rod 36 moves to drive the force transmission plate 37 to move, the force transmission plate 37 moves to contact the sensing color-changing sheet 34, and the sensing color-changing sheet 34 is forced. The sensing color-changing sheet 34 changes color after being forced. If the sensing color-changing sheet 34 returns to the original color after changing color, it indicates that the elastic durability of the arc-shaped spring sheet 24 is good. If the sensing color-changing sheet 34 always keeps the color after changing color, it indicates that the arc-shaped spring sheet 24 has been elastically fatigued, and the staff needs to replace and maintain it in time, so as to ensure the working effect of the arc-shaped spring sheet 24.
